New Audio DAC Offers High-Res Audio to Pro Audio Devices

Cirrus Logic recently introduced the CS43130 MasterHIFI, which is a low-power, digital-to-analog converter (DAC) featuring a headphone amplifier. Operating at 4× lower power consumption, the CS43130 DAC supports Direct Stream Digital (DSD) formats and includes a NOS Filter and 512 single-bit elements to eliminate unwanted noise from the signal and for best filter response. The IC minimizes board space requirements while enabling performance and features to drive design differentiation.Cirrus CS43130

The CS43130’s features, specs, and benefits:

  • Supports DSD, DSD DoP (DSD over PCM), up to DSD128 and all PCM high-resolution audio formats up to 32-bit 384 kHz

  • High impedance of 600 Ω and inter-channel isolation of greater than 110 dB.
  • Proprietary digital-interpolation filters support five selectable digital filter responses.
  • On-board, low-noise, ground-centered headphone amplifier provides proprietary AC impedance detection to support headphone fingerprinting
  • Uses 512 individual DACs per channel in an analog/digital filter array
  •  THD+N of –108 dB and dynamic range of 130 dB
  •  Consumes 23 mW of power
  • Supports up to 32-bit, 384-kHz sample rate audio playback
